Intrepid 6-wheeler Curiosity perhaps protested too much when it tweeted "Yes, I've got a laser beam attached to my head. I'm not ill tempered; I zapped a rock for science." NASA turned the rover's high-powered laser loose with 30 pulses of a million watts each, reducing a thin layer of the chosen stone, dubbed N165 "Coronation," to plasma. The resulting spectrum was then analyzed by the on-board "ChemCam" to determine its composition, and the US/French team who developed the system said it's working even better on Mars than it did on terra firma. The results are now being studied, but if we had a laser beam on another planet, we'd be firing it all over the place -- in the name of "science," of course.

If you want to do what NASA just did, except in Lego form, then look no further. NXT builders Doug Moran and Will Gorman put together this amazing working Curiosity rover that can happily roll around plastic terrains, searching for the answer to Bowie's questions. Four of the six wheels are powered, enabling the gear to make 360 degree turns, while a fully working arm and mast are controlled separately. Of course, nothing we can say could compare to seeing it in the flesh plastic, so head on past the break to see it in action.
